Women's clothing sizes??

[First Otaku]

Hi guys/gals, I was planning on buying some clothes online, but the sizes are to confusing. So I'm trying to see if women's US, size 6, will fit a 16 yr old boy. I'm uh, gonna buy a garter belt/stocking and bra set...any help on the size issues is greatly appreciated, don't want to waste money or mess up on my first buy :p
If you want the link I can paste it, but since it's a link to amazon, and lingerie I'm not sure if it's against the rules.

Usually there will be a size guide, so take your measurements and compare it to what they have in the sizing chart. Women's sizes vary greatly so it can be tricky

I'd measure yourself and go from there like Haley said. Honestly, without any reference, I can't tell you what will or will not fit you.
